disable clearing of /tmp on boot - where is the command in rc.sysinit

ignus · 2011-09-11 10:37:36

Hi there, I want to disable the clearing of the /tmp folder on boot, but I can't seem to find the appropriate line in etc/rc.sysinit.

Apparently this should be the line

/bin/mountpoint -q /tmp || /bin/rm -rf /tmp/* /tmp/.* &>/dev/null

but my rc.sysinit does not contain that at all:

mountpoint -q /proc    || mount -n -t proc proc /proc -o nosuid,noexec,nodev
mountpoint -q /sys     || mount -n -t sysfs sys /sys -o nosuid,noexec,nodev
mountpoint -q /run     || mount -n -t tmpfs run /run -o mode=0755,size=10M,nosuid,nodev
mountpoint -q /dev     || mount -n -t devtmpfs udev /dev -o mode=0755,size=10M,nosuid &>/dev/null \
  || mount -n -t tmpfs udev /dev -o mode=0755,size=10M,nosuid
mkdir -p -m 1777 /run/lock
mkdir -p /dev/{pts,shm}
mountpoint -q /dev/pts || mount -n /dev/pts &>/dev/null \
  || mount -n -t devpts devpts /dev/pts -o mode=0620,gid=5,nosuid,noexec
mountpoint -q /dev/shm || mount -n /dev/shm &>/dev/null \
  || mount -n -t tmpfs shm /dev/shm -o mode=1777,nosuid,nodev

Also the "remove_leftover" function doesn't seem to be about cleaning /tmp... ?

Where is the command that clears /tmp located in this file?

If this is a brand new install, then /tmp is by default mounted as a tmpfs. Take a look at /etc/fstab

It seems shm is my tempfs

Is it not this the purpose of /var/tmp

Your fstab is old. There will be a .pacnew file in /etc.

ignus · 2011-09-11 20:37:38

Indeed, there is a pacnew file that specifies /tmp as tmpfs. Thanks!
What should I do, just delete the old fstab? Or move its contents to the pacnew file?

Indeed, it is the purpose of tmp to be cleared, but i've set it as my default download location and I reboot every day, don't want to lose my downloads every time. Also, I have 10gig on /tmp, no need for it to be cleared each time.

I think cybertorture was saying that you should use /var/tmp for the things you don't want to lose on reboot.

You should carefully merge the .pacnew file with your old fstab, as always.

Sure, if you don't want to be able to boot anymore that is a great way to do it.

I would read and follow https://wiki.archlinux.org/index.php/Pa … save_Files instead though.

And as said, just don't use /tmp as your download location. Specially not since bad things happen if you manage to fill up / if you don't have /tmp on a seperate partion.
